Bone plate with elongated guiding channels

Abstract

A bone plate has bone facing side, a front side being arranged substantially opposite to and facing away from the bone facing side, and at least a first and a second elongated guiding channel. The first and second guiding channels are configured to receive a flexible elongated member such as, for example, a cerclage wire, and the first and second guiding channel are each further configured to guide the elongated member along a respective first and second guiding channel axis (A, B) from a first to a second lateral region of the bone plate. The first and second guiding channel axes (A, B) cross each other in at least one region of the bone plate outer front side.
